Men's CoolPlus F.O.M. Long Sleeve Action Shirt has special cooling features like a vented bi-swing back, wicking CoolPlus ripstop fabric and UPF 50+ sun protection. Secure pockets in all the right places for your man stuff.

One cool Work Shirt - perfect for sticky situations

This is the Work Shirt for men of action, who work outdoors or roam the wildest, hottest corners of the globe. It’s got the high-performance fabric and function to handle any climate, any situation. The CoolPlus ripstop fabric is light yet tough at 3.4-oz.-per-yard, wicks away sweat far more effectively than cotton. Gives you UPF 50+ protection to effectively block 98% of the sun’s damaging UV rays too. Mesh insert panels in the bi-swing back deliver extra cooling power. The clever pockets help you stash all your stuff and keep it secure. (Don't want your treasure map falling out now, do you?) And, like most Duluth Shirts, the F.O.M.™ (Freedom of Movement) features let you work or travel comfortably.

I have one each long sleeve and short sleeve. I like how they dry quickly and wick moisture. The fabric keeps them from clinging to bare skin and allow ventilation. While they are indeed 'cool' they are not cold. They break wind well while allowing air to flow...sounds like a contradiction, but I am sticking with my description.The long sleeve has the advantage of epaulets to hold the rolled up sleeve. This is practical. What first attracted me to these shirts was the vertical zipper pocket. These are great for traveling by air when limited room prevents you from flailing you your elbows to access pockets. I will be getting more. The only negative...maybe because I am not used to it are the huge buttons. They look great, but seem to be more difficult to button than necessary.
